To @ZZ whom t may concern:

Be it known that I, SAMUEL MAWHINNEY, a citizen of the United States,residing at Worcester, in the county of Worcester andV State ofMassachusetts, have invented certain new and useful Improvements inLasts and Hinges, of which thefollowing is a specification, referencebeing had therein to the accompanying drawings.

My invention is an improvement on the last described and shown in UnitedStates Letters Patent No. 601,622, granted to Abel D. Tyler, Jr., March29, 1898.

In the drawings illustrating the principle of my invention and the bestmode now known to me of applying that principle, Figure 1 is a sideelevation of a part of a last, a portion of the fore part being brokenaway to show the hinge member therein. Fig. 2 is a top plan view of whatis shown in Fig. 1. Fig. 3 is a central vertical sectional view on lineA A of Fig. 2. Fig. 4 is a plan View of the fore-part hinge member. Fig.5 is a perspective View of what is shown in Fig. 4. Fig. 6 is a detailview showing in perspective the hinge mechanism which connects the heelpart and the fore part. Fig. 7 is a detail showing the cap and itscoacting spring.

The fore part 1 and heel part 2 are joined by a hinge connection, theopen space 3 permitting these parts to be tipped up relatively to eachother, as is indicated by the dotted lines in Fig. 3. The inner end wall4 of the heel part and the inner end wall 5 of the fore part form whatmay be termed reciprocal hinged surfaces, these two walls abutting whenthe parts are tipped up relative to each other, as shown by the dottedlines in Fig. 3.

Cast integral with the heelplate 6 is the spindle-socket 7 and theheel-part hinge member 8. (See Fig. 6.)

The spindle-socket 7 is adapted to receive a spindle in the ordinary useof the last, and inserted therein is a plug 23, which rests on aninwardly-projecting annular rim 29 and resists the end thrust of thespindle when theheel part is forced thereon.

A wooden plug 28 is inserted in the lower end of the spindle-socket 7 toreceive a lasting-tack.

The heel-part hinge member 8 extends upwardly and forwardly from theheel-plate 6, as is clearly shown in Fig. 6, and the upper front portion9 of the said hinge' member 8 is provided with a pintle-bearing 10,adapted to receive the hinge-pintle 11.

The fore-part hinge member 12 (see Figs. 4 and 5) is preferably formedby bending sheet metal on itself, each fold having a lobe 14, concave onits inner side. The two concave lobes register with each other, so as toform a chamber 15, extending lengthwise of the last. This hinge member12 is secured in the fore part by fasteners 16, (see Figs. 1, 2, and 3,)which pass through the fore part and holes in the hinge member 12.Formed on the hinge member l2 are ears 17 and 18, adapted to receive thepintle 11.

The pintle-bearing 10 of the heel-part hinge member 8 enters the space19 between the ears 17 18 of the fore-part hinge member 12,and these twocoactin g hinge members are secured together by the pintle 11, as isclearly shown in Fig. 6. The pintle-ears 17 18 are preferably of unequalwidths, as shown, so that the fore-part hinge member 12 may be used oneside up in right lasts and the other side up in left lasts.

The top surface 19 of the end portion 9 of the heel-part hinge member 8is a cam-surface, and the said end portion 9 is also formed with ashoulder or bearing 20, against which the cap 21 (see Figs. 7 and 3) isforced by the spring 22. The said cap 21 is slidably mounted in thechamber 15, and when the heel part is tipped up relatively to the forepart, or vice versa, the cam-surface 19 engages the outer end 0f the cap21, the cap being thereby moved toward the toe against the tension ofthe spring. The fore part and heel part are kept in alinement in theposition shown in Fig. 1 by the spring 22 pressing forcibly the cap 21against the shoulder 20. Through the hole 30 in the spindle socket 7 andlthrough the wooden plug 28 passes a fastener .24, which secures thesaid spindle-socket 7 in place in the heel part 2. and 3.)

The heel-part hinge member 8 is mounted in the vertical slot 26 in theheel part 2 and (See Figs. 6, 2,

IOO

is held securely therein by a fastener 25, which passes through the heelpart and a hole 27 in said hinge member 8.

It is not necessary to my invention that the spindle-socket 7 beintegral with the heelplate 6 or the hinge member 8, for all three partsmay be separated, if preferred.

What I claim isl. The combination, in a transversely-divided last, of afore part and heel part with a hinge, one member of which is secured tothe heel part, and the other member of which is secured to the forepart, one of said members having a pintle-bearing, and the other memberhaving two pintle-receiving ears, one of which is narrower than theother.
